Here is a resource where algebra learners show their understanding of a system of equations involving a circle and a line. Once graphed, learners see two points of intersection, one where the ordered pair is read, and a second where...

Students explore hurricanes.  In this weather data interpretation lesson, students draw conclusions about the impact of Hurricane Floyd as it related to weather conditions. Students read and interpret a tide data table, a barometric...

Consider the preponderance of evidence when making a verdict. The third of five lessons in Unit 1: The Big Climate Change Experiment focuses on the evidence for climate change. Learners study graphs, diagrams, and pictures regarding...

Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

Can you graph your story? Keep your classes interested by challenging them to graph a scenario and interpret the meaning of an intersection. Be sure they paty attention to the detail of a graph, including intercepts, slope,...

Students are read a book and discuss what is meant by different fractions. Using the internet, they practice converting fractions into decimals. In groups, they create their own line fraction after watching a demonstration by the teacher.

Is the inverse a function? Scholars learn how to examine a function to answer this question. Using an online interactive, they examine the properties of inverse functions to compare to the original function.

Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Who knew there were so many fun educational opportunities featuring pasta? Scholars read a brief informational text about the history of pasta (note that "macaroni" is spelled two different ways, so address this if kids are reading...

Math modeling is made easy with the first installment of a 16-part module that teaches pupils to model real-world situations as linear relationships. They create graphs, tables of values, and equations given verbal descriptions.

Good things happen when algebra and geometry get together! Continue the exploration of coordinate geometry in the third lesson in the series. Pupils explore linear equations and describe the points of intersection with a given polygon as...

Second graders explore clouds. They read The Cloud Book by Tomie dePola. Students sort the cloud pictures into three categories. Students create a graph using the cloud pictures. They use Excel to create a bar graph.

"Plot the plot" of "The Adventures of the Speckled Band" with your young readers. Take a few days to read Sir Arthur Conan Doyle's short story as a class or in pairs, having learners write down what they consider to be the most important...

Students investigate plant growth. In this plant growth lesson, students investigate what would happen to plants if they did not have water and sunlight. Students conduct experiments to determine what plants need. Students create a...

Seeing how seeds grow into plants is such an enjoyable for students! They plant lima bean seeds and take pictures to record the growth of their plants. Students write in a journal to describe their daily observations of their plants, and...

Students investigate data collection and analysis.  In this Algebra I instructional activity, students create a scatter plot and find the equation of best fit in a simulation of a leaking water pipe.

Physics lab groups finagle with laser lights to determine the critical angle of refraction for both water and Lucite. Because there are no detailed steps or an answer key for this enlightening exercise, an inexperienced physics...

Students define vocabulary words. In this geometry lesson, students identify the graph as a line, ray or segments. They understand the properties of each and calculate the distance on a number line.
